Let i ,j and k be the vectors of the canonical basis of R3R3.

Let

u = i +3j -2k and v =-2i -j +k

(a) Evaluate the following orthogonal projection:

proj u (v )=

ANSWER FORMAT: Write your answer in the format Ai+Bj+Ck. eg, 3i+2k or (2i+3j-5k)/4.

(b) What is the angle (in radians) between u and v?

=( rad)
